I have an EA from others, which copies, reads and writes csv file in MQL5/FILES folder under metatrader. It's too complicated, much over my coding knowledge but still I want to revise it a bit. So I did a simplified experiment and I found that, with tester, I can not copy file to the real MQL5/FILES folder. (without tester, it works.) (CopyFileW in kernel32.dll is used here.)
Is there any workaround? without this, I can not use debug tool to figure out some weird problems - I guess debug tool must work with tester ?
